.pipe 20, each of Inain exhaust pipeV QLthereWith forming an` i t basin 24 in the check valve 25,

p BEST AVAILABLE leads from the exterior of the vessel at the top of the conning tower to the interior of the vessel. Attachedy to this intake nozzle 8 is a three-way valve 9, which isconnected to an auxiliary intake pipe l0 and to the niain inlet pipe 11. The three-way valve 9 1s so arranged that air may be drawn into the pipe, 1l either ,through the. intake nozzle 8 when the conninlel tower of the vessel projects above the Surfaceof the Water or when the vessel isrentirely submerged air may be drawn from the interior tower through the auxiliary intake pipe 10. The inlet pipe 11 extends through the end partition 4, and has connected thereto short sections of pipe 12, which are in turn, connected to the middle of individual kinlet pipesv 13'of inverted U shape. Theendsof the individual inlet pipes pass through the cell cover 14 at diagonally opposite corners of-eachcell. An intake manifold isf thus formed 'by the pipe 11, the short pipe 1 tions 12 and the individual inlet pipes 13. Into the center of the cell cover 14 is screwed a.' plug 15, which has a hole therethrough, and extends downwardly into the cell; In the lower lend of this plugV is supported by arms 16, acup 17. lnto the hole of this plug 15 is screwed a cap 18, which has an opening in it, arouud which is a 'flange 19, which extends downwardly into thecup 17; This cupl 17, extending as it does over the ange 19, prevents any of the electrolyte of the battery from being drawn outy through theA outlet pipe, opening of this cup in each cell is a, short which is connected; to the exhaust "manifold The exhaust pipe 21 leads to the exh austfan and then to the conning tower, where it is connected with the exhaust nozzle 21, in which is a closing: velve 28u In the exhaust pipe 21, and in the inlet pipe 11, there. are catch basins 24,-,

which collect an)7 water which may leal;y into ithe pipes leading from the conning tower.-

Each sealed cell casing comprises the battery jar 26 and the cover 14, sealed therein by a ring of pitch or tar 27. Within the casingare. the plates the terminals 30 and 3l respectively lead through the cell cover 14 at points between the points of entrance of the inlet pipes 134 and the point of exit of the cutletpipe From the structure Whlch has beende-- scrihcd it is seen that a. means has been provided for conducting pure air to the interior Y.
